Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive fumes, hydrogen bromide (see ICSC0282) and bromine (see ICSC0107).
The substance decomposes slowly
under influence of
light
and
moisture
producing corrosive hydrogen bromide.
Reacts vigorously with powdered aluminium or magnesium, metals such as sodium, potassium and calcium, strong bases and strong oxidants,
causing fire and explosion hazard.
Attacks fats, rubber, some forms of plastic, coatings.
Occupational Exposure Limits:
TLV: (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: skin absorption (H);
Carcinogen category: 2;
(DFG 2004).
OSHA PEL: TWA 20 ppm C 30 ppm 50 ppm 5-minute maximum peak
NIOSH REL: Ca TWA 0.045 ppm C 0.13 ppm 15-minute See Appendix A
NIOSH IDLH: Ca 100 ppm See: 106934
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour,
through the skin
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
The substance may cause effects on the
central nervous system
, resulting in
lowering of consciousness
.
Effects of Long-Term or Repeated Exposure:
Lungs may be affected by repeated or prolonged exposure causing bronchitis.
The substance may have effects on the liver and kidneys.
This substance is probably carcinogenic to humans.
Animal tests show that this substance possibly causes toxic effects upon human reproduction.
